Bonds Aren't Inversely Corroused During a Stock Market Drawdown

The modern financial portfolio is built upon the assumption of stocks and bonds being inversely correlated during a stock market drawdown. What's happened as inflation has reemerged for the first time, meaningfully, since the 70s, obviously bonds have sold off. But what hasn't been taken into effect is that one of the biggest drivers of stock market financial asset returns to the last decade is stock buybacks. And how do they finance stock buybacks? They just borrowed money at the end. Yeah.
