    Apple admits repair business hurts their bottom line

    Apple is not your friend. 1.Your response initially sounds good but you are not mentioning that Apple installed this "fix" on your phone without telling you. 2.Also their dogmatic insistence that you can not repair your Apple product is another indication that Apple is not your friend...

    Apple admits repair business hurts their bottom line

    This is just wrong. It is like saying that you can not fix your car. Apple has long fought efforts that would make iPhones easier to repair: It has lobbied against right to repair efforts in several states, doesn’t sell iPhone replacement parts, sued an independent repair professional in...

    How do I avoid market glitches in the future?

    Don't trade. You will be gliding along, think that, thinking, wow I must be almost a genius at least and then, you will get your ass handed to you. What to do? The truth each and every time is this. No matter what has happened in the past - small trade, small profit - many, many - times.

    AAPL's guidance significantly lower, trading halted

    The only thing I groked from the last Apple upgrade is that it did facial recognition. Actually the worst thing possible. Before to find you they needed you to have your phone with you. Now they only need to be able to find you face. Rumor was that the next generation of Apple products was...

    Dumb luck..........?

    Yes you experienced "dumb luck". The current market is not the time to become enlightened on how the ES works. If you start now to make 15 trades a day you would probably blow out your account in less than a month. Better to just do red/black in Vegas. If you are really serious. Paper trade...

    Deglobalisation And The Fall Of China

    In Vietnam during the war there were many US military units that were 70-80% strung out. This was not lost on the Chinese. If you think the enterprise behind drugs in the US is Mexican well whatever. There are several groups/counties at large , working day and night, to bring the US down...

    Deglobalisation And The Fall Of China

    The US is in deep decline. Our reliance on Indians and Chinese is beyond belief. I have lived in Asia for many years. To think that have any allegiance to the United States, our core system of history and values, is foolish. I actually left academia because in each and every graduate...

    SPY options bid ask spreads

    Do you watch option prices? In many they slam the bid to the wall. Meaning - we do not want to trade here. Caveat - This is for individual stocks. Not sure if the same pattern is for indexes but would suspect they are but less extreme.

    The S&P 500 bottomed today on 12/20/18

    Something odd is going on here. There is a vested interest in keeping prices high. Most are compensated in part as a % of assets under management. We are getting close to the end of a quarter. Couple this with mark to market - where a little can make a big difference. Meaning there should...

    SPY options bid ask spreads

    Bid ask spread is a function of expected intraday volatility. When no one knows what is going on the bid ask spread gets larger. "I know, but the ask moves, just not the bid." When a market maker sells an option, money is made. When you buy an options you only make money when you sell...

    Trading Volatility and Skew

    I will never say anymore about this except - sitting on a lot of updated code is some very simplistic origins. Think - War Games. Not only the stock market but in many, many, different places.

    Extreme panic

    Volume is picking up a little bit on the downside but no where near panic. What has to happened is some or one very large highly leveraged trade has to belly up. It was like in the market collapse of 2008 when positions were leveraged 50 to 1. When positions like this start to go down there...

    Range Bound Identified Within An Hour

    Not sure what most of the above means. Sounds like you were saying the market was slow or maybe fast. Regardless there was money to be made on the swing. However, I agree, it was tedious to participate. The bigger reality is that there is selling into any rally. Perhaps end of the year tax...

    Not a big fan of Jim Cramer but this article is at the heart of what is going on in the market - Jim Cramer: The Common Stock Buyer Seems to Have Disappeared We have, for lack of a better term, what acts to be a 'broken' market - both ways - because the volume is so thin...

    I found this article interesting - https://www.cnn.com/2018/11/30/health/gene-edited-babies-he-jiankui-intl/index.html The actual process, HIV resistance, is minor. The meta is that germ line research is being done. This is one of many, many, experiments being done in secret around the world...
