"What about last year when he said to add on any dip below to 1450 or under?"
Brinker's newletter is written for long-term investors, and he only recommends major Sells when he sees a long-term market top; which preceedes a Bear market.
I don't subscribe to his newsletter any more, but I think he considers the current market a deep correction, and not a Bear market, because any S&P drop (from last October closing highs) greater than 20% hasn't held for more than a few days. He uses corrections as buying opportunities, so there is some method to his madness, so to speak. If it's a big correction, he calls it a Gifthorse buying opportunity. I think his current Buy level is S&P 1300 (or very near there). He only uses closing prices, so 1300 would be the touch of an S&P 20% decline. Apparently he continues to believe S&P wont drop below that level for more than a few days.
