  • 2 Stocks To Buy As Employment Rebounds, 3 To Avoid [View article]
    Jack Welch is the last guy in the world who should complain about somebody fudging the numbers.

  • Apple's Hyperbolic Orbit And Newton's Laws Of Gravity [View article]
    scott trader, it's nothing to do with light being faster than gravity - or slower. It's the same velocity for both as I explained earlier.

    The reason light cannot escape a black hole is that at the Schwarzschild Radius (aka event horizon) the escape velocity required becomes equal to the speed of light itself.

    Gravity is essentially curvature in the spacetime continuum, according to Einstein's General Theory of Relativity (the Special Theory lacked generality because it failed to take gravity's effects into account).

    As such, it doesn't make any sense to say that gravity is slower or faster than light, any more than it would to have a coin with only one side.

    They are both aspects of the same thing. Hence, gravitational effects propagate at the speed of light.

    Imagine if the Sun were to disappear this very instant. It would take around 8 minutes for us to feel the effects - either from light or from gravity because that's how long it takes light to travel from the sun.The effects of both would become apparent at the exact same instant (which you wouldn't have to worry about for much longer afterwards!).

    Colin, the answer to your question is Yes. It will still propagate at the speed of light.

    The fact that the speed of light (in vacuo) is fixed across all reference frames, including those which may be in relative motion to each other, is what in fact gives rise to all the weird relativistic effects such as length contraction and time distortion as described by the Lorentzian equations in the theory of special relativity.

  • You Don't Have To Be Brilliant To Do Well In The Stock Market, Just Don't Be Stupid [View article]
    Best article of the year so far. This is wisdom distilled and, for the long-term investor, wisdom begets money.

    As the author says - the greatest enemy of any investor is impatience.
    On the flip side, patience is the greatest virtue. It's also the hardest trait to learn.

    Light is an electromagnetic phenomenon and magnetism cannot propagate faster than the speed of light.

    The linkage between electricity, magnetism and the speed at which light propagates is elegantly shown by Maxwell's equation:

    EoUo = 1/c^2

    Eo = permittivity of free space
    Uo = permeability of free space
    c = speed of light in vacuum

    Eo here relates to electric fields and Uo to magnetic ones.

    I knew it was only a matter of time before someone set a price target of infinity on AAPL.

    Clearly, your gravity analogy is nonsense. As an object leaves a gravitational field its weight goes to zero (while mass remains constant). As AAPL tries to go 'hyperbolic' however, it's financial weight (ie the market cap and the earnings needed to support that at a given P/E) becomes ever heavier. That means that - unlike Saturn 5 - it cannot forever escape natural limiting factors such as market saturation, margin erosion, pricing power, rising input costs.

    I'm not saying that AAPL is out of gas, but that this gravity analogy is nothing but moonshine.

  • Large-Cap Gold Miners Continue To Underperform Gold [View article]
    It does seem like it will be a cold day in hell when the large-cap miners finally outperform gold.

    However, on one score they do outperform - yield.

  • ETFs That Offer Overseas Gains With A Currency Kicker [View article]
    DXJ looks the best of those options by some distance.

    Pity it's already had quite a rapid run-up though. But then, so has pretty much every other risk positive asset..

  • Russia will lift its ban on grain exports on July 1, Vladimir Putin said yesterday, as 2011 spring planting was 10% higher than in 2010 and the winter wheat harvest was good. The government had banned grain exports in August last year after a severe drought cut production by 37%.  [View news story]
    Given that they've been talking about this topic in the grain markets for months, there's just a tiny chance they may have discounted it already.

  • Five stocks that could push the Dow to 14,000, according to 24/7's Jonathan Berr: MSFT, JPM, HPQ, GE, HD. Each has underperformed the broader market YTD but boasts at least a 20% upside to consensus estimates of Wall Street analysts, Berr believes.  [View news story]
    MSFT as one of the stocks that can take the Dow to 14K?

    Thanks.. that's one of the funniest things I've seen here in a long time!

    MSFT can't even drive itself out of the ditch that Ballmer drove it in to.

  • How to surf the silver wave: Maybe it's time to take some profits, and wait and see, James Stewart says. He's big on inflation hedges, but you might want to take this chance to rebalance. Meanwhile, Jim Rogers gets into the Grantham camp and is bearish on silver short-term, but still bullish on (peaked) oil.  [View news story]
    They must be pretty dumb to hand over silver coins at a 10% discount to spot.

  • 7 High Growth Stocks Becoming Deep Value Buys [View article]
    INTC is an outstanding buy but the majority of analysts seem to hate it with a passion (though they adore froth like Netflix).

    Fine - just makes it cheaper for the likes of me. Everytime INTC drops to $20 or below, fill your boots with stock. I'd even be happy to sell puts around that price.

    RIMM is also looking an attractive value play. It's not going to outcompete AAPL by any means but then again it isn't priced that way either. Instead it's priced as though its business model is entirely dead. The reality is that it still has a strong customer base and they're showing very strong growth in the emerging markets.

  • Get ready for a tidal wave of lawsuits, as industry experts say U.S. regulators are likely to file up to 100 lawsuits in the next two years against the executives and directors of failed banks. To date, the FDIC has brought just six cases.  [View news story]
    Jamie Dimon says: "There isn't a prison yet built that can hold me".

    With apologies to John Dillinger, and no offence is intended to his memory in comparing him to Jamie Dimon.

  • Fed Vice Chair Janet Yellen warns against taking the foot off the gas, saying conditions aren't ripe for the Fed to exit its unconventional policies. Some colleagues, including Richard Fisher, have warned the Fed should stop "spiking the punch bowl" or risk rampant inflation.  [View news story]
    Yellen is part of the privileged Gang of Three alongside Bernanke and Dudley (who as head of NY Fed has a permanent seat on the voting council).

    It doesn't matter how many hawkish statements come from Fed chairmen in Kansas or St Louis or Boise, Idaho, as the Gang of Three have by far the most clout in deciding monetary policy and nearly always get their way.

    Unfortunately, all three of them are inflationist maniacs.
