Over the past month the Twitter Top 10 portfolio was down over 1% even though the S&P 500 Index was up. Ironically, the largest drag on the portfolio was Twitter (TWTR) which was down over 25%. Another thing of note for TWTR is our trading strategy called a sell signal for TWTR in mid September based on a loss of momentum from traders on Twitter. This illustrates a few points I try to make often. First, the trend of momentum is the thing that is most important when timing the purchase of stocks. The second is that you should never buy this list blindly on the first Friday of the month.

The Twitter Top 10 portfolio is intended to be an illustration of a mechanical momentum portfolio and how it performs during different market conditions. The strongest (most bullish) lists are intended to be a starting point for your stock selection, then the trend of momentum should help you time your purchases and profit taking or selling. If you had been watching the trend of momentum for TWTR you would have waited until it indicated that the consolidation was likely over.

Today is the first Friday of the month so we replace the portfolio with the 10 stocks with the strongest support on the Twitter stream over the past month. Here’s a list with the candidates.

Below is a performance chart and details of last month’s holdings. I’ll update the list with today’s closing prices sometime over the weekend.
