3 tools to help identify new investments
We’ve compiled a list of research stocks to keep an eye on, but the stock market is volatile and trends can change daily.
If you’re actively trading stocks, staying on top of new industry trends and rising stocks can take a lot of time. Here are some of my favourite tools to keep up with trends and get new trading ideas.
- Stock screeners. You can use an online stock screener like Finviz or TradingView to see what stocks are making the biggest moves today and narrow your search by industry and market cap. Screeners are most beneficial for technical traders who have set criteria in mind for their trades. For example, if you’re looking for stocks trending today in the medical industry, you can pull a list of all mid-cap and large-cap stocks for that industry and sort by percent change since opening.
- Newsletters. Some of my favourites include the Motley Fool Stock Advisor and the Alpha Boost and Cherry Picks newsletters published by Tastyworks. Newsletters can be a great way to find companies that may be worth investing in for the long haul.
- Social media. While I’d never make a trade based on a Reddit thread alone, social platforms like Reddit, Twitter and Tiktok can be useful tools for staying on top of what companies people are talking about. The trendiness of a stock can directly influence its price – but those trends can also be volatile. While social media can occasionally help buy-and-hold investors, it tends to be a more practical tool for active traders.
