From all indications today, the uptrend should continue as perfect buy signals have developed today. Today for example a couple of the tech bellwether companies had great earnings news after the close yesterday leading to a major rally in the Nasdaq Index. Focusing on a technology ETF, QQQ, it broke to the upside sharply. There is a possibility for a minor pull back within the range of $149 to $148 and if you get this brief opportunity, you should add a position in this ETF, the stocks within this ETF, or similar ETF next week.
I know you are concerned that you missed the move. There is no way the market can trend higher. I will be buying at the high if buy now. Yes these are rational thoughts, but based on past experience I would expect a buy in rally early next week with some short term sell off (within the day) that quickly returns to new highs. From there we let it ride until the sentiment of the market tells us otherwise.
