> Bots and HFT systems are designed to make lots of money quickly. [poster]
They may be originally designed with that in mind but lately mostly provide needed market liquidity. This was extensively covered here recently so why the FUD?
Because I believe with a high degree of certainty that it's true: http://www.economist.com/news/books...overs-more-shenanigans-wall-street-fast-times
The HFTs’ trading edge comes from two different sources. When an investor presses the button to deal, that signal is sent to a broker or bank, who in turn is supposed to search the many different stock exchanges for the best price. But because of the time taken for trading signals to be sent down the wire, those orders arrive at different stock exchanges at separate times.
The HFTs were sitting in wait, and used their advantage to exploit the time differences.
Often, the HFTs place buy or sell orders for small amounts at individual exchanges. When those orders get filled, that is a signal that a big investor has a much bigger stake to offload. Sometimes the HFTs’ orders are designed not to be filled, but to flush out which way the institutions are planning to trade; HFTs comprise half of all trades on the American market but submit almost 99% of the orders.
Perhaps the best analogy is with the people who offer you tasty titbits as you enter the supermarket to entice you to buy; but in this case, as soon as you show appreciation for the goods, they race through the aisles to mark the price up before you can get your trolley to the chosen counter.
> I recommend that most people ignore wild movements and hold their shares for a long time. [ac13.7]
Being LONG does not necessarily mean one never sells shares, that is being a 'lazy long'. Profits cannot be reinvested so grandchildren or charities greatly benefit in future? Passing up profits makes no sense; holdings should be managed. Profits are how you increase your corpus. Short term price moves ARE important to Long term investors.
Describing normal volatility as 'wild' to excuse not participating at all, ever, is a head-in-the-sand stance. If you stipulate that ER time specifically is off limits for trading stocks, then that would be understandable.

The caveat is that I also recommended an exit strategy in several of my other posts.
I've observed that most people buy high and sell low. It seems to be a psychological peculiarity of the human species, and I've read that the emotional impact of fear of loss is 2x that of happiness from gain. I made my recommendations because I don't think it serves people to run for the exits whenever TSLA slides $10-$20 when nothing fundamental has changed about the company.
I actually do agree that holdings should be managed. My retirement accounts are largely low-cost index funds that I re-balance once each year, or when the difference in asset allocation from my target percentages reaches a certain amount. Holdings in individual stocks are basically bets on 10x, 20x, or more growth over a decade or more. I don't pursue any strategy of optimization here because I don't have the time to worry about short term trading, and because I'm OK with getting a good return, not an optimal return. Maybe I'll lose out on making a couple extra $, but that's a trade off I make in order to reduce stress. Yes, I am a "lazy" investor http://www.bogleheads.org/wiki/Lazy_portfolios However, I am also disciplined in my approach:biggrin: Most people here seem to be active traders and have some holdings in derivatives. I think that's ok, so long as one accepts the risk. I just like to share my strategy too, and attempt to prevent panic among those who may be reading the thread (but not participating) and worrying.
