Market Intelligence Service
The DXI is an index showing the DRAM output value changes, which is comprised of the output and price variations.
1.1 DXI Purpose
The main purpose of the DXI index is to provide users with an easy to understand graphical representation of the DRAM industrys market trend. The index is calculated by multiplying the mainstream DRAM chips with their respective street price. The calculation is performed under a logical framework, providing users with a powerful tool in gaining a detailed insight of the market performance.
1.2 Understanding the stock price changes through the DXI index
The DXI index not only reflects the output value of the DRAM industry, it also depicts the stock price changes of DRAM makers. According to statistical data compiled by DRAMeXchange on the stock price of relevant DRAM makers, such as Qimonda, Nanya, ProMos and PSC, a strong correlation is seen with the spot price. Therefore, the index provides users with an accurate account of the highly volatile memory business.
The DXI is a DRAM output value index, used to assist relevant DRAM specialists, analysts and fund managers to track the DRAM price and output trend. DRAMeXchange makes use of two important criteria in selecting the chips. First, the spot price of related chips must always be able to be maintained by DRAMeXchange. Second, the selected chips must reach our benchmark, and contribute over 70% of the chosen DRAM makers output. Once the selected chips fail to meet the criteria, DRAMeXchange will renew its DXI calculation base.
Listed are the chips that comprise the DXI index for January 2006: |

DRAMeXchange collects the output data on a monthly basis. The September data is arbitrarily chosen to represent the output for Oct 1st. It is multiplied with the October chip price to serve as the calculation base period.
Q: How do you develop DPI and how can I use DPI as a trading reference?
A : By combining the DRAM historical prices with a technical analysis, DRAMeXchange comes up with a novel way to project volatile DRAM prices by using DPI.
DRAMeXchange has developed the following DPIs which are the most popular and useful in terms of interpreting the DRAM price trend.
MA - Frequently used in technical analysis, a moving average is an indicator that shows the average value of DRAM prices over a period of time. Moving averages can be used to predict the direction of a trend.
Golden Cross: A crossover involving DRMA prices' short-term moving average breaking above its long-term moving average, a sign that indicates a bull market.
Dead Cross: An indication that suggests a bear market on the horizon.
RSI - A technical indicator that compares the days when DRAM prices finish up against when they close down.
MTM - The act of recording the prices to reflect the pace of an uptrend or downtrend in market value
When a rise in MTM coincides with an uptrend in the moving average, it suggests growing momentum will push prices higher.
When MTM and the moving average diverge, it signals the prices have peaked and will head south soon.
KD - A momentum indicator that shows the location of the current close relative the high/low range over a set number of periods.
It consists of two lines:
%K compares the latest closing price to the recent trading range.
%D is a signal line calculated by smoothing %K.
WR - A momentum indicator especially popular for measuring overbought and oversold levels.
Bias - An indicator to calculate the deviation between price and MA.
Q : How do you collect the DRAM spot prices and contract prices?
A : The DRAM spot prices on the DRAMeXchange website reflect the price performance of the global DRAM spot market. They contain three major market segments: Mainstream, Graphics, and Legacy items. All prices on the website are collected from worldwide spot markets, and they are struck prices rather than offer or inquiry prices.
The spot prices are collected by DRAMeXchange from five major players in the industry:
- DRAM Vendors
- OEMs and Systems
- Channel distributors
- Module Makers
- Brokers
Each segment consists of representative companies and their price quotes are weighted by the volume. Before the close of trade, DRAMeXchange will liaise with the sales department to scrutinize the prices that the representative companies offer. After examination and calculation, the average spot prices will be updated at aforesaid times. For more information, please contact at 
Q : How often do you update the DRAM / NAND Flash spot prices and contract prices?
A : DRAM/NAND Flash spot prices:
DRAMeXchange updates the spot prices 3 times a day at
* 11:00am (GMT+ 8:00), including prices from morning Asia trade and a recap of the market close in Europe and United States.
* 14:30pm (GMT+ 8:00)
* 18:00pm (GMT+ 8:00), including the closing prices of the Asia Pacific markets and opening trade in Europe
Q : How often do you update DRAM contract prices?
A : DRAMeXchange updates the contract prices twice a month after DRAM makers and PC OEMs reach an agreement on contract deals. Negotiations on contract prices begin on the 1st and 16th day of every month and they usually take 3 business day or sometimes longer to finalize the deal. DRAMeXchange will post the final contract prices right after they are set by both parties, usually on the 6th and 20th of every month.
NAND Flash
Q : How often do you update NAND Flash contract prices?A : The negotiated deals and quote announcement of each major NAND Flash vendor differs slightly. Thus, DRAMeXchange timely announces the current NAND Flash's contract prices twice a month. The NAND Flash contract price is updated twice a month. (Announced between the 5th ~10th and the 20th -25th)
Q : What is the definition of NAND Flash's current contract prices
A : The current contract prices of NAND FLASH are the settled prices agreed between the buyers and sellers for a specific amount of shipment over a specific future timeframe. Most industry players usually set their contract price within an effective timeframe, ranging from one week to a month. The contract prices we gathered exclude those special deals that sellers negotiated with a limited group of strategic customers, when large purchases are made.
Q : How NAND Flash contract prices are presented?
A : As the negotiation period and quote announcement is slightly different between each major NAND Flash vendors, DRAMeXchange in principle announces the current contract prices twice a month. In light of the ever-changing emerging memory market, the method of the price release is always aptly adjusted.
Q : What is the Methodology of the NAND Flash contract pricing
A : DRAMeXchange conducts our estimate and assessment of current contract price interval via direct or indirect survey with NAND Flash associated companies (including vendors, distributors, agencies, system makers, OEMs, memory card makers, etc.) regarding their outlook over the price trend. We also take the spot prices trend for side reference.Moreover, the methodology of NAND Flash spot price collection is similar to DRAM spot price.
Q : How do DRAMeXchange define the high, low, and average of NAND Flash contract prices?
A : The high and low points of NAND Flash contract prices on DRAMeXchange's website represent the highest and lowest settled prices within the current period.
The average NAND Flash contract price is the average collected weight of the settled price by volume trading.
Q : How is the NAND Flash contract prices classified on DRAMeXchange website?
A : The types of NAND Flash contract prices on DRAMeXchange website is based on the following criteria:
- Product type (MLC & SLC)
- Density type (2Gb, 4Gb, 8Gb…etc.)
Q : What are the differences between SLC NAND Flash and MLC NAND Flash?
A : There are two major types of NAND Flash memory in the market: SLC (Single-Level-Cell) chips and MLC (Multi-Level-Cell) chips. MLC architecture allows 2 bits of data to be stored in one memory cell, while SLC architecture allows just one. Therefore, the density per chip cost for MLC chips will be lower than SLC chips. However, as the architecture of MLC chips is more complicated than SLC chips, the product life cycle, security and speed of data transfer for SLC chips is better than the other.
