Where's The Flow? XLK And Technology Stocks


In recent posts, we've looked at Adjusted Relative Dollar Volume Flows for three market sectors: materials, financial, and energy. We've also seen how dollar volume flows capture sentiment within the S&P 500 stocks. Now we ask the WTF question about the technology sector: Where's The Flow among the stocks in this sector? Representing technology, we have the XLK Spyder ETF for tech stocks. As with the other sectors, I have taken five individual stocks that dominate that sector ETF to assess Dollar Volume Flows: MSFT, INTC, IBM, CSCO, and VZ.

Once again, we have the blue line representing the price of the ETF going back to January, 2004, and we have the pink line representing the 10-day average Adjusted Relative Dollar Volume Flows for the five tech issues. When we have flows above the horizontal red line, it means that we're seeing above average dollar flows into the sector; when we have flows below the red line, it means that we have below average dollar flows.

Patterns that we've seen in the sector data to date seem to hold up for the technology stocks. Specifically, we can see that peaks and troughs in dollar flows tend to precede intermediate-term price peaks and valleys. We can also see that dollar volume flows for the technology issues have been in decline well before the recent market drop. These divergences seem to be common as part of topping processes across sectors and markets.

Finally, notice a pattern that we've seen among the financial and energy stocks: since the recent market decline, dollar volume flows have continued at subnormal levels. In fact, eight of the last ten trading sessions have seen below average dollar flow into the tech issues. What that tells us is that, once again, traders are not leaping to pour money into technology stocks, even at these lower prices. Until we see evidence of large market participants returning to the market and putting their capital to work buying these shares, the tech sector is vulnerable to further selling.

Dr,

Do you think your Adjusted Relative Dollar Volume Flows would work well on the futures markets to assess if the large traders are entering or exiting the market? Another idea might be to check your Adjusted Relative Dollar Volume Flows against the change in open interest and the COT reports.

Great work -this is really a helpful look at what's happening beneath the prices in the markets.
I'm curious where you gather data from -I know that several of the trading platforms/packages allow the user to code indicators, etc. -so one can gather one's own data (but only up to a point). I also know of the many data providers that collect and sell data. What do you use to set up a study such as this one?

On another note, I've never gotten along well with the flow indicators I've watched (such as On-Balance Volume). I'd love an indicator (and tried to code a couple, but the tick by tick data-gathering is pretty hard on the processor). Any recommendations?

Thanks again.

Hi John,

Yes, I think the data would work well in the futures markets. In a sense, that's what the Market Delta program is doing. It would be interesting to track longer-term flows vs. OI and the COT data. Thanks for the suggestion!

Hi,

I gather my data from RealTick and process the data in Excel. That's pretty much how I do all my analyses for the blog.
