If you are not thoroughly enjoying the recent dip and can't wait for your stocks to fall further to bargin levels to buy some more (like an item you want to go on sale), perhaps you should consider a balanced fund - wherein the impersonal computer buys on the way down and sells on the way up to hold a fixed asset balance.
Even after thirty years of investing - the rational part of my brain still gets 'frozen' / overwhelmed by the emotional part - so I gave up about ten years ago - moved my 7-8 Vanguard mostly index funds to Lifestrategy (quasi 60/40 balanced). Kept 10%, now 15% in hobby stocks looking for bargins.
Pogo(the cartoon) - If you look yourself in the mirror and see - 'I have met the enemy and I is them' - perhaps balanced index or even a timed asset class like Vanguard Target Retirement is for you.
Or - I have discipline - yes, yes - I love slice and dice - Bernstein, Coffeehouse await.
Chickenheartedness being one of my all time favorite investment theories - 75% balanced index out of the can, 10% REIT Index to counterbalance/boost yield(super mini Bernstein) and for the joy of watching falling markets to buy 'bargins/dividend stocks' - about 15% putz or mad money.
Back in the 70's (when I was a legend in my own mind) - I played with with warrants and did things like borrow short/bought mortgage REITs long. As time passed - it was a wash with wins/losses canceling each other.
Male hormones being what they are - if golf or tennis doesn't do it - then perhaps a speculation or two at the edges - I don't recommend confusing it with real ER. In the old days, if I had a 'win' - it was live large party time. Meanwhile - plunka, plunka slow moe DCA (autodeduct) got me to ER.
