Even broad market indexers are having a good time.</p><p>The <a target="_blank" class href="https://markets.businessinsider.com/index/s&p_500">S&P 500</a> is up by almost 34% in the last 12 months. Meanwhile, Vanguard's <a target="_blank" class href="https://markets.businessinsider.com/etfs/vanguard-total-stock-market-index-fund-etf-shares-us9229087690?miRedirects=2">Total Stock Market Index Fund</a> (VTI), which tracks the full range of investible US stocks, is up by 32% for the same period.</p><p>But what happens when things start to pull back, because they ultimately do?

Those who have been investing for a while know it's best not to stitch your wagon with the crowd if you want to skip some of that volatility and even beat the market.</p><p>It's why billionaire investor Ken Fisher takes a contrarian approach. But it's not as simple as going against the crowd. According to his book, "Beat the Crowd," a savvy investor should have the insight to cut through the noise to see clearly.

He's pegged as a value investor because he hunts for strong, undervalued companies with a competitive advantage. He buys them and then lets time take its course as the rest of the market slowly realizes what he has.</p><p>Some have taken to <a target="_blank" class href="https://www.businessinsider.com/warren-buffett-investing-strategy-approach-top-fund-manager-rich-eisinger-2020-1">copying the so-called investing gurus</a> of our world.
