Commentary
The S&P 500 (SPY) closed below 1800, one of the signals I have mentioned triggers a short on the index. However, sellers could not hold the close, and the S&P 500 ended up bouncing neatly off its 20DMA. This uptrend has performed very poorly as support, so I have no strong expectation that it will hold firm this time. However, if the S&P 500 gaps up or opens strongly tomorrow (Wednesday, Dec 4th), I would be inclined to interpret this as confirmation of support and NOT an opportunity to fade.

T2108 quasi-oversold conditions add to the big caveat and the odds for follow-through to the bounce. Even with the bounce from the lows, T2108 is down 15.6% over two days, qualifying for quasi-oversold status. I prefer to play quasi-oversold from bigger (and more dramatic drops) because the error rate for projections of upside tend to be better. See the chart below:

The error rate for the T2108 Trading Model (TTM) is a relatively high 35% at the -15% 2-day drop for T2108, barely worth a trade. The TTM projects a 63% chance of upside tomorrow.

All things considered I think bears are better off standing down UNLESS the S&P 500 moves below today’s low.

I conclude with this chart of Tesla (TSLA). The stock rocketed higher 16.5% on the heels of several news items:

I indicated in other forums that TSLA could be a key tell for the universe of high-flying, speculative stocks. From today’s reaction, it is clear there remains plenty of buying interest! A huge test is likely coming at the overhead resistance from the 50DMA.
