In yellow is the TSLA/NVDA spread or ratio, and here it shows the jump off the all time lows with the huge price spike post Musk vote.
With spread charts you can gain clues on future price action based on the other ticker. For the continued TSLA bull case, we get a pull back in the ratio to form the right shoulder of the IHS and then continue upwards.
In that case as long as NVDA continues to consolidate or trend up TSLA will remain bullish too (and outperform).
