My wife and I are finishing up some major loans, and are planning to put some of our money into investments once the loan is completely paid off - this will happen in, at most, 3 months.

But, I have noticed on the news that the stock market is taking a significant hit due to the United States' new tariff policy with China.

On the one hand, this means that stock trends are down - making investments in the short-term ill-advised. But, on the other hand, if stock prices are down, it means there's more room for growth in the long-term, and this is meant to be a long-term investment (I'm putting this money in to grow for several years).

So, is it wise for me to invest in stock as soon as possible to take advantage of the price dip? Or is this not a wise strategy?

  • Is it a wise strategy to invest in stock as soon as possible to take advantage of a price dip? 100 years ago, Will Smith offered good advice on this subject: "Don't gamble. Take all your savings and buy some good stock and hold it till it goes up, then sell it. If it don't go up, don't buy it." Commented Jun 19, 2018 at 19:47

    And yet, dollar cost averaging, rebalancing a portfolio, buying or selling at a target price are all forms of timing. Commented Jun 20, 2018 at 17:55
  • @Daniel: Don't try to time the market in the short term. In the long term, see the comment about the difference between buying the S&P at its peak in '09, vs at the bottom in '09. Personally, I wouldn't put much into stocks for the next couple of years unless something changes radically, and am looking to gradually move 2-3 years living expenses into something less volatile. But that's just my opinion: further discussion might belong on the Politics site :-)

You say: "I have noticed on the news that the stock market is taking a significant hit due to the United States' new tariff policy with China." and then you follow up saying: "...stock trends are down...".

Maybe you should look at the charts below:

S&P 500 Daily Chart S&P 500 Daily Chart

S&P 500 Weekly Chart S&P 500 Weekly Chart

The daily chart of the S&P 500 show that prices have just started a new uptrend from April 2018, and have just fallen slightly from their recent highs.

The weekly chart of the S&P 500 shows an uptrend from early 2016, which almost ended in early 2018, but has not yet developed into a downtrend, rather it is somewhat going sideways. It could recover (as the daily chart suggests) and develop into a new uptrend if prices go above 2802, or if prices fall below 2553 it could develop into a downtrend.

You would generally look at daily charts for a medium term timeframe of months to a year or two, and at a weekly chart for longer term timeframes of years to decades.

So don't believe everything you hear in the news, it usually does not represent what is actually happening in the markets.

If you were looking to get into the market for the long term, say 5 years plus, I would wait. If prices move above 2802, then jump in as this is confirmation of a new uptrend commencing. If prices fall below 2553, keep waiting and don't buy, as this is confirmation of a new downtrend starting, and you shouldn't buy until the downtrend is over.

In my view, based on the daily chart uptrend and how close the current price is to 2802 (only 40 points away as of the 19th June 2018), I would be expecting a new uptrend to commence in the next week or two.


The price fluctuations on any given day with respect to your entry point will be negligible. The exception to this is if the company's executives are all indicted or some other DEFCON 1 scenario that causes the share price to implode. What I'm trying to say is that if your investment horizon is long enough (think decades), it won't make much difference. The S&P is down today so obviously your initial investment of $X will buy more, but the virtues of compounding make it so you should not pay too much attention to such entry points. It's all about buy low sell high, so what you suggest is not a bad idea.

Let me put it this way: If you bought the S&P in the summer of 2008 before the GFC (Great Financial Crisis), you would still have positive returns today.

    Yes, daily fluctuation is noise. But entry price can make a significant difference even if one has a long term investment horizon. Yes, if you bought the S&P at its peak in 2008, you would have positive returns today. But if you bought it at the end of the collapse in March 2009, you would have 3.25 times the profit versus that purchase in 2008. 3.25X is not a negligible. Commented Jun 19, 2018 at 20:12
  • Theoretically yes, but it's essential to note that your strategy requires timing the market, which is notoriously unreliable, especially over long periods of time, and even more so for DIY investors. Most people are much better off simply investing whatever they can every month into low cost index funds, and holding until retirement.
