Confiez une somme de £5000 à une équipe de financiers aguerris et la même somme à un chat, en l’occurrence nommé Orlando.
Qui gagne à la fin ? Le chat bien sûr.
[…] Each team invested a notional £5,000 in five companies from the FTSE All-Share index at the start of the year. After every three months, they could exchange any stocks, replacing them with others from the index.
By the end of September the professionals had generated £497 of profit compared with £292 managed by Orlando. But an unexpected turnaround in the final quarter has resulted in the cat’s portfolio increasing by an average of 4.2% to end the year at £5,542.60, compared with the professionals’ £5,176.60.
While the professionals used their decades of investment knowledge and traditional stock-picking methods, the cat selected stocks by throwing his favourite toy mouse on a grid of numbers allocated to different companies.
The challenge raised the question of whether the professionals, with their decades of knowledge, could outperform novice students of finance – or whether a random selection of stocks chosen by Orlando could perform just as well as experienced investors.
The result indicates that the “random walk hypothesis”, popularised in economist Burton Malkiel’s book A Random Walk Down Wall Street, is perhaps truer than we thought. Burkiel’s book explores the idea that share prices move completely at random, making stock markets entirely unpredictable. […]
The Observer, Mark King: “Investments: Orlando is the cat’s whiskers of stock picking.”

Je ne connaissais pas non plus cette trappe à spam (quoiqu’il y a une majorité des messages que je n’aurais pas classés comme tels spontanément).
Pour rire, j’y ai trouvé ça :
Si j’avais un cerveau endommagé en phase terminale je tomberais peut-être dans le panneau.

Merci Laurent pour l’information sur ce dossier “Autre”, je n’étais jamais allé regarder et j’y ai trouvé deux messages datant de plusieurs mois que j’aurais bien aimé avoir. J’en ai parlé autour de moi et je ne suis pas le seul.

‘tain, vous déconnez, les mecs. Je connaissais l’existence de cette boîte alors que je n’ai même pas de compte FB.
Blah ? Touitter !
