投資を初め投資続けることが大事。下記のチャートを見て分かる通りタイミング投資は非常に難しい。相場の良い時と悪い時はcluster together(房をなす、鈴なりになる、群生する、密集する)になっていることが多い。過去20年の上昇相場10回の内、6回は暴落相場10回の中の2週間以内に起こっている。暴落時はノイズを無視することが最善の方法です。

The bottom line, however, is that the key to successful investing starts with getting invested, and then staying invested. As shown in the chart below, trying to time the market is extremely difficult, particularly when good days and bad days tend to cluster together. In fact, over the past 20 years, six of the ten best days occurred within two weeks of the ten worst days. The best approach during this period was to ignore the noise.

Asset markets are inherently forward looking, and the reality of the situation is that although 2020 is now underway, you cannot invest with 20-20 hindsight. Some things in the coming year will go right, while others will go wrong; the key is to build a portfolio that can keep your clients comfortable as the market twists and turns.

Get invested, stay invested
