The portfolio return is the sum of the weighted returns of the individual classes. The returns of the individual classes are determined at the end of the period, after each class SD has been accounted for (rolled up into the class return)...and consequently rolled up into the portfolio return. IOW, ...
Doing a full backward-looking mean-variance optimization the only inputs are the returns and the weights for each investment. The interaction among the classes/investments is derived from the returns. In a roundabout way you can see why backward-looking analyses have significant limitations. That's ...
The ideal is to build a portfolio which will deliver, say, 8% per year with zero volatility. Then your planning is straightforward. In the real world the portfolio SD is going to cause the portfolio return to fall below 8%, so we try to minimize deviations from 8% in order to keep our plan on track....
I have doubts about rebalancing back to a DIY AA. Is there any reason to believe an initially arbitrary AA is efficient or will be efficient over the long run?
Once transferred you should qualify for a free Vanguard Brokerage Account, you could then gain access to PAUIX which would be a great complement to Wellesley Income (Admiral shares). An even split between VWIAX and PAUIX would be great, although I'd probably tilt a bit toward PAUIX.
My bonds are actively managed, they're also highly diversified. I think my PIMCO fund holds bond funds managed by Gross and I have no problem with that. I think multi-sector and strategic income funds are good options for those looking for a highly diversified bond fund, they're the all-encompassing...
I'm not sure HFs are necessary. I referred to the growth vs inflation model when I built my portfolio, I referred to many other things as well. While asset classes don't quite fit as neatly into that macro model as the diagrams show at minimum the model provides the rationale behind asset classes in...
Last night they showed the episode of Seinfeld in which George convinces Jerry to go in on a stock with him, Cendrex. After several days of losses Jerry bails and locks in a $1,500 loss, George decides to stick it out. A few days later, out of curiosity, Jerry and his girlfriend check the stock in t...
With 45 years to go you are contemplating exactly the opposite approach I would take if I were in your situation. I would adopt a highly diversified conservative or moderate portfolio to reduce risk and take advantage of compounding over so many years to grow my portfolio, rather than relying too he...
I don't like reaching into the past for comparisons, the past is the past. But as a result of some simplistic research I did a year ago... Between 73 and 82 Wellesley just missed keeping pace with inflation, Wellington didn't fare so well. Recall, Wellesley runs about 33/67 (stocks/bonds) and Wellin...
After years of investing and my own research I've come to the conclusion the rule-of-thumb recommending large stock allocations for young investors is just the opposite of what I would do if I had the chance to do it all over again. The long horizon translates to assuming less risk, not more. If one...
I think 100% bonds is under-diversified too, although if you were intent upon such a portfolio you might consider multisector and strategic income funds. A healthy dose of alternative classes would also be wise. I share your concern over stock volatility and whenever this comes up I always mention t...
I get your points. I'm not sure a lot of securities means better diversification. I think I could have picked a better word than static for the TR funds, slowly changing might have been more appropriate. In any event TR funds make big bets on when the stock and bond markets should be heavily weighted.
Using the low ER index approach can lead to one of two problems: 1) If you adopt the fund-of-funds approach you end up with limited diversification within a static AA. 2) If you choose to go with a number of targeted index funds you assume responsibility for portfolio management. There may be other ...
I have a small amount of HY, my fund managers see value (for now) and I don't second guess them. I personally wouldn't own HY if I managed my portfolio because the misleading long term correlations don't hold during crises. I've come to the conclusion downside protection is paramount, as opposed to ...
My objective is not to realize the highest return possible, my objectives are to meet my portfolio value target at the time I retire and then make that money last through my retirement. So while I may pay somewhere between 15 and 20% over an extended time period for management it's worth it to me. W...
Wellesley uses a static AA and is geared for low/moderate inflation environments, IBR has a dynamic AA and should be able to handle higher inflation too.
The fund is an attempt to distribute volatility evenly, so your stocks don't drive the whole portfolio into the ground. The volatility-spreading is coupled with macro risk considerations, like growth and inflation. The main mechanism for volatility reduction is the big bond allocation, with leveragi...
I invest to meet my future retirement needs. Bogle's restricting himself to capital markets, which I think is generally a mistake. I'm not sure how a dollar gained in precious metals or foodstuffs is different than a dollar earned in capital markets. Prices are determined differently in each of thes...
I would stay broadly diversified, going 100% real assets doesn't seem like a balanced approach from an asset allocation perspective. I don't see Arnott as prone to wild speculation or scare tactics, he's a smart guy and a good manager. I have about 25% of my retirement assets in his All Asset All Au...
While I think Swensen is a great manager I doubt he's the only one who knows the ins and outs of alternative investments, many of them are accessible to investors. I'm not buying your claim about higher return translating to higher risk. While there aren't any guarantees with asset allocation manage...
I'm not sure what the problem is with holding alternative classes, conventional stock and bond portfolios like Wellington, Wellesley, etc. didn't keep pace with inflation between 73 and 82 although Wellesley came close. Wellington lost about 33% from its peak in late 2007 between 2007 and 2009. Alte...
While I appreciate the idea of investors getting to the party too late I disagree with much of what's been posted so far. I haven't conducted comprehensive research but from what I have seen some institutions have done well using actively managed portfolios which contain alternatives. I realize aver...
