With TSLA, backtesting the overbought and oversold signals of the RSI (especially the 80/20) shows it's been pretty reliable in providing buy and sell signals over a longish timeframe. Trading using the RSI alone is generally thought of as being a bad strategy, but with a couple of confluent signals it could be pretty useful here. Some stocks seem to favour the RSI more than others. We could also see some divergence (which I need more time to learn properly!) I'm learning Technical Analysis and how to trade generally, but this one seems like a strong signal to watch for this stock. Of course these types of signals would probably work much better while the stock market is generally strong.
