😰 The Stock Market Has It's Worst Week Since September

😬 The first week of March was a rough one - with the stock market recording its worst week since September. Here’s how the major indexes performed:
S&P 500: -3.3%
Nasdaq 100: -3.8%
TSX: -2.6%
Bitcoin: -13.1%
📈 But even though the week was rough overall - on Friday, Jerome Powell (the Chair of the Federal Reserve who sets interest rates in the US) fueled a small recovery (+0.6% for the S&P 500) after saying the economy was in a good place:
Despite elevated levels of uncertainty, the U.S. economy continues to be in a good place. The labor market is solid, and inflation has moved closer to our 2 percent longer-run goal.
✨ And while Friday’s jump was a nice relief - I’m sure many of you (especially the beginner investors) are still worried about your portfolio. So, before I dive into some of the other market news this week, let’s talk about it…
😰 Long-Term Investors Shouldn’t Panic
⏰ It’s a tale as old as time - when the markets start to dip, investors start to panic.
💡 And I get it, it can be scary to see hundreds (or thousands) of your hard-earned dollars evaporate overnight. So for the newer investors reading (and hopefully as a helpful reminder for even the more experienced folks), here are 3 quick tips during these volatile markets:
1) 📈 In the Long Term, the Market Goes Up
It’s very easy to get caught up in the short-term swings in your portfolio, but if you’re investing for the long run, the occasional market correction is par for the course. To illustrate, here’s the annual returns in the S&P 500 over the past 30 years (pulled from Blossom’s IG account where we post lots of helpful images like this):

🔴 If you look month-to-month, red months are even more frequent. In the 396 months from 1992 to 2025, the S&P 500 only had a positive return in 62% of the months:

🎯 If you’re investing with the plan to sell in a few months or a few years, these swings can definitely be painful, but if you have a long time horizon, you don’t need to worry too much about short-term fluctuations. Some months will be red, and others will be green - but overall, stick to your plan and remember in the long run, the market goes up!
📈 Over the past 20 years, the market has returned an average of 11.8%!
2) ❌ Don’t Treat Your Stocks Like An Index
⭐️ Tip #1 is especially true for index investors - who buy and hold a market index like the S&P 500 - which is diversified across the top 500 companies in the US and auto-rebalances as the companies go up and down in value.
🤔 But what about those of us who hold individual stocks instead of, or alongside, the index? Well, in an amazing post by @ronan on Blossom he says something simple, yet very important:
“STOP treating your companies and stocks like an index”
💡 Ronan points out that companies are not the same as an index and, unlike the S&P 500, might not continue to go up even in the long term (as they are driven by the success/failure of the underlying business).
🤔 So, what does this mean for investors who hold individual stocks? Well most importantly, when you bought the stock you should have had a clear thesis about why you think the company is a good investment. If the stock dips, ask yourself if anything has fundamentally changed about that thesis.
⚖️ Not all ‘dips’ are created equal. For instance - Palantir dipped when the government announced budget cuts at the Department of Defense. That’s a real fundamental change that is going to hurt the underlying business. Now that doesn’t mean in that case you should dump all your Palantir stock, but you should take the time to re-evaluate and see if you need to update your thesis and plan about the company.
🚘 To use an example from my own investing, when Tesla soared over 100% between the November election and late December I decided to sell my stock, as from my perspective nothing had fundemantally changed about the company to warrant such a massive increase. Since then the stock has fallen nearly 50% (back down to pre-election levels).
3) 👀 Market Dips Can Be a Great Test
✨ From my perspective, this week’s dip is a great thing for new investors as it’s a perfect test of whether your portfolio actually matches your risk tolerance.
⚠️ The problem when a market is going up and up and up, is investors (expecially beginners) start building riskier and riskier portfolios - weighting heavily into tech, investing aggressively into small-caps, and chasing the double-digit returns they see other investors making.
🧐 If that’s your strategy, and you have a clear thesis around all your stock picks and are comfortable with the risk you’re taking on, that’s one thing. But if not, you should take this dip as an opportunity to step back and re-evaluate if your portfolio actually matches your goals, time horizon, and risk tolerance (+ read some of the awesome posts in the Featured Discussions section at the end of the newsletter)

💸 Exciting New Launch – Global Dividend Stocks with Tax-Efficient Income
🌎 When it comes to buying global dividend stocks outside of Canada, there are a couple of drawbacks. For starters, buying only high-dividend-paying stocks can often reduce the total return of the portfolio since these stocks tend to be in low-growth areas of the market, such as telecoms, consumer staples and real estate. Another drawback in buying global dividend paying stocks is the fact that the dividends are typically taxed at a higher rate than Canadian- eligible dividends.
🎯 Rather than reaching for yield from global equities, taxed at the highest marginal tax rate in Canada, the newly launched Guardian i3 Global Dividend Premium Yield Fund (the “Fund”) targets attractive global stocks demonstrating strong and consistent dividend-growth rates, while seeking to boost the Fund’s monthly distribution yield through tax-efficient1 covered call premiums. Based on our Guardian i3 Global Dividend Growth Fund, this new Fund aims to mirror the stock-picks of Guardian Capital LP’s i3 InvestmentsTM team2 that is at the forefront of AI-utilization3 to screen for and analyze some of the best stock opportunities globally.
