Stocks Always Go Up....Eventually

Silver Imac Displaying Line Graph Placed on Desk

Investing comes with a lot of noise. Changing trends, politics, forecasts, the list goes on. Countless factors influence the stock market. Moving it up and down, sometimes aggressively in a matter of moments.

A sudden decline is a scary prospect, leaving new investors hesitant to dive in. Nobody wants to invest $1,000 only to have it be worth $900 by day's end.

Unfortunately, the ups and downs are part of the game. The good news is that the ups are a lot more persistent than the downs.

Taking a look at S&P 500 returns from 1926-2015, you can see that as more time passes, the greater the odds are for a positive return.

	Probability
Time Horizon	Positive	Negative
Daily	54%	46%
Quarterly	68%	32%
Annually	74%	26%
5 Years	86%	14%
10 Years	94%	6%
20 Years	100%	0%

If you're investing for a day, you're pretty much gambling. It's a coin flip whether you'll come out on top. The odds shift greater and greater towards your favour the longer your time horizon. Of course nothing is guaranteed and past performance is no indication of future performance, but the data is convincing and it makes sense when you think about it.

When you own a stock, you're business owner. When you own a diversified portfolio, you own a lot of businesses. If you believe businesses as a whole will continue to innovate and grow, it's reasonable to believe that stocks over time will provide a positive return.

Diversification is key here. Most stocks on their own are terrible investments, many providing negative returns no matter how long you hold them for.

Stocks collectively however perform well over the long term. The S&P 500 averages about a 10% return annually. It's never a consistent return mind you (it can get pretty volatile), but the point is, over time stocks rise. Patience, my friend.

Market noise can create a bumpy ride for investors, but if you're a long term investor with a well-diversified portfolio, you can ignore the daily noise and enjoy the expected positive returns.

Today's Special: Humble Pie

You champion a project, fight for an idea, and then...reality sets in. That churning in your stomach isn't butterflies, it's the realization you've missed the mark. Pride will puff up your chest, and kick in the "defend at all costs" instinct. But arguing with the umpire never changed a call. Admitting you're wrong isn't a sign of weakness. It can strengthen your professional standing. In a world obsessed with the illusion of infallibility, the courage to adjust course is a breath of fresh air. It shows you're confident enough to be wrong, and adaptable enough to learn from it. Do your research, think critically, and stand behind your decisions. But when the data whispers (or screams) otherwise, don't be afraid to swallow that slice of humble pie. Be the first to acknowledge. Don't wait for someone to point out your mistake. Be open, take responsibility, and most importantly, focus on what you're going to do to address it. Don't dwell ...

Negative Feedback, Positive Lessons

In the battle against plastic bags, a five-cent tax was shown to be much more successful at deterring usage than a five-cent credit for bringing your own bags. Carrots satisfy but sticks sting, and they sting hard. So we default to the less painful choice of avoiding loss. Loss aversion impacts the way we process information. A 2019 study invited participants to learn through a series of multiple choice questions. Each question only had two options to choose from. Whether guessing correctly or not, they would still learn the right answer. Despite the identical learning opportunity, participants were much more successful at recalling the answers they guessed correctly than those they got wrong. "You're right!" feels good. We savour the moment, analyzing every detail. "You're wrong!" stings. We want to quickly forget, dismiss, and move on. When we succumb to loss aversion, we miss opportunities to learn. Failure is part of the process. We'll experie...

Starting Really Really Small

On your desk is one of the most intimidating sights known to man. A blank page. The prospect of filling it up with anything resembling decent seems insurmountable. Staring at the long road ahead fills you with anxiety and dread. The first step is the most difficult. So we procrastinate. We " research ", we " prep ", we " plan ". We do everything except tackling the problem. We avoid the pain for as long as we can. To make a blank page less intimidating. Tear it in half. There, half as scary, twice as easy. Still too much? Do it again. And again. Keep doing it until the task is so small that it's too easy not to do. Getting starting is the hardest part. So make the hardest part as easy as possible. This doesn't guarantee amazing results, but it gets you in the game. You can't win if you don't play.
