President Trump's plan for a sweeping tariff on steel and aluminum imports is causing investors to worry about a possible trade war. Fidelity's John Gagliardi joined Cheddar to provide insight into market movements.

Gagliardi breaks down how to approach the markets through three charts. He walks us through long-term, medium-term, and short-term graphs to highlight key takeaways in historical market patterns.

Gagliardi points out that in a short-term chart, you can see the new normal in the S&P 500 is higher highs and higher lows. This is a sign that we're still in a secular bull market, according to Gagliardi.
