That’s kind of what I aim to do at work. Sadly, even when you’re right about a sector you have the same problems you always do, mostly regarding timing the exits / entry.
Like right now, say you exit your 20% tech to the tune of dropping to 10%. You shift that 10% to energy expecting summer demand to kick up. Your logic was right, but you were early by 2 weeks and if you did Jack shit, you would have made significantly more. You didn’t calculate the pure retard strength of ‘this stock is up big, me buy’ That’s usually how it goes for me anyway.
