Bearish divergences building up in the Tech space: Bears out of the wood?

Bearish momentum divergences are a consistent sell signal for single name equities and equity indexes like the Nasdaq.

Similarly, Apple has formed a large bearish divergence on the weekly chart. AAPL's weekly RSI is back in the 'overbought' 70 range:

Last but not least, there is near-term bearish divergence developing as well on Nvidia. While the stock price is hitting new highs, the RSI Relative Strength Index (short-term momentum) is hitting new consistent lows.  

Moreover, the price to sales ratio of NVIDIA Corp has hit all-time highs this week - over 20x. This level is even more than its internet-bubble highs. 

Beware of the bears out there!
