English term or phrase: random walk theory

Definition from The Economist:
Also random walk hypothesis. Impossible to predict the next step. efficient market theory says that the prices of many financial assets, such as shares, follow a random walk. In other words, there is no way of knowing whether the next change in the price will be up or down, or by how much it will rise or fall. The reason is that in an efficient market, all the information that would allow an investor to predict the next price move is already reflected in the current price. This belief has led some economists to argue that investors cannot consistently outperform the market. But some economists argue that asset prices are predictable (they follow a non-random walk) and that markets are not efficient.

Example sentence(s):

The most well-known practical example of random walk theory occurred in 1988 when the Wall Street Journal sought to test Malkiel's theory by creating the annual Wall Street Journal Dartboard Contest, pitting professional investors against darts for stock-picking supremacy. Investopedia
The random walk hypothesis has merit in dissuading investors from trying to make guesses about short-term stock movements. However, many long-term investors still manage to invest well by putting time on their side. The Motley Fool
Malkiel and the random walk theory provide considerable support to the intimidated individual investor, but Malkiel in particular encourages investors to understand the theories and investment methods that the random walk theory challenges. Investing Answers

Croatian translation:Teorija nasumičnog hoda

Definition:
Nasumičan hod je matematički, odnosno fizikalni pojam, koji opisuje putanju koja se sastoji od uzastopnih nasumičnih koraka opisanih određenim matematičkim veličinama, npr. cijelim brojevima. Upotrebljava se za opis bilo kojeg procesa kod kojeg ne postoji nikakva predvidljivost ili pravilnost u kretanju izmežu pojedinih koraka, odnosno u promjenama vrijednosti sistema u ovisnosti o nekoj drugoj veličini, npr. vremenu.

teorija "slučajnog puta"

Definition from tportal:
Teorija da ne postoji predvidljiva pravilnost u kretanju dionica, tj. da se cijena dionica kreće nasumično (random walk teorija).

Example sentence(s):

Istraživanjem se utvrdilo da Black- Scholes model za utvrđivanje cijene opcija ima nekoliko slabosti kao što su pretpostavke da se kursevi dionica kreću linijom slučajnog puta i da je njihova varijanaca tokom vremena konstantna veličina. - CROSBI

Teorija nasumičnog hoda

Definition from own experience or research:
Nasumičan hod je matematički, odnosno fizikalni pojam, koji opisuje putanju koja se sastoji od uzastopnih nasumičnih koraka opisanih određenim matematičkim veličinama, npr. cijelim brojevima. Upotrebljava se za opis bilo kojeg procesa kod kojeg ne postoji nikakva predvidljivost ili pravilnost u kretanju izmežu pojedinih koraka, odnosno u promjenama vrijednosti sistema u ovisnosti o nekoj drugoj veličini, npr. vremenu.

Example sentence(s):

Nasumičan hod je najjednostavniji primjer stohastičkog procesa. Stohastičkim procesomnazivamo niz pokusa gdje ishod svakog pojedinog pokusa ovisi o slučaju. Dakle, to je nizpokusa koji se odvijaju kontinuirano s vremenom, a rezultat svakog pokusa je slučajan. - Osijek University

Explanation:
"Random walk" odnosno "nasumičan hod" je opći pojam koji se upotrebljava u bilo kojem odgovarajućem kontekstu, ne samo u ekonomiji i financijama. Izvan čiste matematike najčešće područje primjene je u atomskoj i molekularnoj fizici, odnosno općenitije u statističkoj fizici.
