The chart of the week shows bull and bear markets for the S&P 500 since 1926. Usually bull markets, when markets go up by 20% or more, last much longer than bear markets and on average last over 7 years. Bear markets, when markets drop more than 20%, tend to be much shorter and last a little over a year on average. Bear markets have occurred 11 times since 1926 and occur around every 7 and a half years. Long story short, if you are invested in the markets long enough you will likely experience both! So be prepared for the ups and the downs.
