Bullish, But a Sell Signal Flashes

Stocks fell sharply yesterday on worries that Fed Chair Powell might be replaced, but then quickly recovered the losses when that proved to be only a rumor. Still, the $SPX chart is strong and the market internals – while overbought in some cases – generally remain positive. There is now resistance at 6300 (this week’s high). There are several support areas: 6200 (this week’s low), the previous highs at 6150, the gap at 6020–6060, and finally 5920. A drop below 5920 would change the chart, and it would no longer be bullish. We don’t expect that to happen, but one can never be certain.

A full McMillan Volatility Band (MVB) sell signal has occurred. The target for this trade is for $SPX to trade at the –4σ band, which is currently at 6030 and rising rapidly. The trade would be stopped out if $SPX were to close back above the +4σ band, which is at 6300 and moving sideways at the moment.
