Is Now a Good Time to Invest in Stocks?

Written by Jim Norris · NorrisAI AlphaLens · Updated August 2026

Quick answer: For long-term investors, the honest answer is almost always yes — if you're buying quality businesses at reasonable prices and holding for 10+ years. The question "is now a good time" is usually the wrong question. The right questions are: what am I buying, what is it worth, and do I have enough time horizon to ride out any near-term volatility?

Why "is now a good time" is the wrong question

The question assumes you can predict whether the market will be higher or lower in the near term. You can't. Neither can professional investors, economists, or anyone else with consistent accuracy. Decades of research have shown that market timing — moving in and out based on macro predictions — destroys more value than it creates for most investors.

The better question: is the specific stock or fund I'm considering priced at a level that offers an adequate return over my investment time horizon?

What actually determines whether now is a good time

Your time horizon

If you're investing for 20+ years, historical data is overwhelming: there has never been a 20-year period in US market history where stocks delivered negative real returns. Starting at a market peak in 1929, 2000, or 2007 still resulted in positive real returns over a 20-year horizon. Time horizon matters more than entry timing for long-term investors.

If you need the money in 2–3 years, stocks may not be appropriate regardless of current prices — not because of market timing, but because of the mismatch between your time horizon and the asset's volatility profile.

What you're buying and at what price

Market-level valuation matters at the extremes. Investing when broad market valuations are at historical extremes — very high P/E ratios, very high price-to-sales — has historically produced lower forward returns than investing at normal valuations. This isn't market timing; it's basic valuation awareness.

For individual stocks, the question is always specific: is this company priced below what it's worth given its growth prospects, competitive position, and risk profile?

Professor Jeremy Siegel of the Wharton School has documented that investors who stayed fully invested through every market downturn — 1929, 1987, 2000, 2008, 2020 — earned dramatically higher long-term returns than those who tried to sidestep the declines. The cost of being wrong about timing exceeds the benefit of being right. — Stocks for the Long Run, McGraw-Hill

What to do instead of asking "is now a good time"

1. Set your asset allocation first. Decide what percentage of your portfolio should be in stocks based on your time horizon and risk tolerance — not based on market direction.
2. Use dollar-cost averaging if lump sum investing makes you anxious. Spreading purchases over 6–12 months reduces the risk of investing everything at a short-term peak.
3. Research individual stocks for genuine margin of safety. Rather than asking whether the market is good to buy, ask whether specific stocks are priced below their intrinsic value.
4. Start now with what you have. The most common regret in investing is not "I started at the wrong time" — it's "I waited too long to start."

Professor Burton Malkiel of Princeton University has consistently argued that time in the market beats timing the market. The investor who starts early and stays invested earns dramatically more than the one who waits for the perfect moment — which never comes. — A Random Walk Down Wall Street, W.W. Norton

When caution is genuinely warranted

Extreme market valuations — when broad indices trade at multiples far above historical averages — have historically been followed by below-average long-term returns. This isn't a reason to avoid the market entirely, but it is a reason to be more selective about what you own, ensure adequate margins of safety on individual positions, and have realistic return expectations.

How AlphaLens helps at any market level

AlphaLens focuses on individual stock valuation — regardless of what the broad market is doing. The Fair Value Stress Test shows whether a specific stock offers a margin of safety at today's price. The Macro Sensitivity Analysis helps you understand how a position would behave in different economic environments. You can find well-priced individual stocks even when the broad market looks expensive — and you can find overpriced individual stocks even when the market looks cheap.
