It's always better to buy shares when the share price is lower rather than higher.
A business is the same business whether its share price is $10, $9 or $11. If I were a shareholder and I were to never buy another share again I'd want the share price to be $11. But I'm going to be buying shares for decades to come.
So it's days like today that can throw up opportunities to buy shares of your favourite ideas at a lower price. Being greedy when others are fearful is very good advice.
It's incredible that world share markets are being moved by many billions of dollars by announcements made through Twitter. But here we are.
I'm not looking to invest every last dollar of cash that I own this week, but I think it's probably a good idea to put some to work at these lower prices. Perhaps some people will invest directly into some US shares that have fallen heavily like Apple.
But for ASX investors, the best way could be to indirectly invest through indirect means like exchange-traded funds (ETFs) such as BetaShares NASDAQ 100 ETF (ASX: NDQ) and Vanguard US Total Market Shares Index ETF (ASX: VTS).
One of my own holdings, Magellan Global Trust (ASX: MGG), has dropped 1.4% today and it's at a 3.3% discount to the net asset value (NAV) per share/unit. It's generally better to buy shares when they're at discount to their value. One of the main features of the investment strategy of its investment manager Magellan Financial Group Ltd (ASX: MFG) is that it constructs its portfolios to fall less than the market on down days but it rises at around the same pace as the market going upwards.
WAM Global Limited (ASX: WGB) is another globally-focused investment business which has fallen today, it trades at an attractive discount to its underlying assets value and it's targeting a solid dividend yield over time.
An Asian-focused ETF like Vanguard FTSE Asia Ex Japan Shares Index ETF (ASX: VAE) could also be an opportune thing to invest in with investors seeking safer places for their money.
Foolish takeaway
I think there are plenty of opportunities that are trading cheaper thanks to President Trump's latest actions. I'm very likely to put some money to work this week and take advantage of the lower prices.
