SPY - How much longer can you go up?

Here's the thing, Indexes are freaking crazy. Everyone knows it and quite frankly, 2020's run was insane! Markets don't normally move at that rate of increase forever. What I'm seeing is the market has been completely over bought. Watching it kind of prep for a retracement is interesting. I had expected it to retrace already but I think it's try to extend itself for as long as possible. Right now, I'm not so positive about it.
