Warren Buffett - Should You Buy At The All Time High?

When Warren Buffett shares his wisdom, I pay close attention. However, there's one topic he hasn't directly addressed: whether passive investors should hit pause on their ETF and index fund contributions when markets are significantly overvalued. Over the past year, the S&P 500 has consistently climbed to record-breaking highs. Does this suggest that passive investors might be better off waiting to see if the market takes a breather?
