Market may be ripe for a correction with the 130 year old curse

Time.com called it the 130 year old curse of the stock market, and it is referring to the unlucky 7. For full article, please refer to here. Why unlucky 7? If you looked at the historic of the US markets, during these periods of 2007, 1997, 1987 and 1907, these were the bear market with the biggest correction.
Expanding on the above, Dana Lyons, a partner at J.Lyons Fund Management wrote a blog post with the observation of the magnitude of the  correction for each of these periods and more. You can read more of his blog post here.
Below is a tabulated extract from his post.

Few more weeks and we will be out of 2017, and the curse will be broken?

The simplest way to forecast expected return of the market

Recently I saw an interview below on John Bogle asking his view on the current market, and I thought it was really an interesting and simple way of using it as a guide. John Bogle, who is the founder of the Vanguard Group, shared this method which he had been using for some time. You can find the full video here.
Essentially, it consists of 2 main concepts; of

Investment Returns + Speculative Returns

Dividend Yield + Earning Growth +/- Change in PE ratio

Investment Returns = Dividend Yield + Earning Growth

Speculative Returns is the change in emotion of people in the market on how much they are willing to pay. 

John Bogle also admitted that no one can predict the future, however he advised investors to stay on course, don't move money here and there, and keep investment simple. These are very good advice.

And today, most of the markets, apart from China, is hitting all time high. Both our sovereign funds released their result last week and they also observed that it is getting difficult to find value in the current market.
